--- Begin Message ---Package: cppcheck Version: 1.65-1 Severity: normal Dear Maintainer, I checked my program in C++ using the "cppcheck -q --enable=all --template=gcc ../" And I think that I have faced with a false warning. My function performs a some action when entering the loop - each time except the first. Boolean variable (flag of first entry) is declared before the cycle and is initialized to "true" (first entry). It is assigned a "false" (re-entry) inside the loop. Example: /* forward.cpp */ int main() { bool first_time = true; while (true) { if (first_time) { first_time = false; } else { // do something } } } Cppcheck does not detect errors in this code. But my code was written a little differently, though he worked the same way. My code is: /* backward.cpp */ int main() { bool first_time = true; while (true) { if (not first_time) { // do something } else { first_time = false; } } } Output of cppcheck: backward.cpp:4: style: The scope of the variable 'first_time' can be reduced. backward.cpp:10: style: Variable 'first_time' is assigned a value that is never used. I think that it is wrong, because these two pieces of code perform the same. Also, if to follow this recommendation of cppcheck, code meaning changes completely.
